IMPROVEMENT IN COTTON-G-IS.

' The Schedule referred toin these Letters Patent and making part of the sante.

To all whom it lnur/ 1l concern Be it known that we, CHARLES Lnnvrr'r and W. H. unnrnen, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in CottonGins; and we do hereby declarethat the following is a full and complete description of the same, reference being had to the accompa nying drawings, making part of this specication,` in which- Figure l is a side view of the gin.

Figure 2 is a view of the top.

Figure 3 is a view of the rear end.

Figure 4, a longitudinal section.

Like letters of referencerefer to like parts in thedifferent views.

' In iig.4 l, A represents a frame, which Amaybe of any desirable size and shape, along the upper edges of which are placed and secured the timbers B, iig. 2.

On the front end of said timbers is mounted, on the shaft G, a roller, D, constructed of rubber or of any other elastic material..

E F are pulleys fixed to the outer end of the shaft, andby which thev roller is driven, as and for a purpose set forth hereafter.

Below, and a little in advance of the roller D, is a small ro11er,G, iig. 5, journalled in a box connected with the frame. The position of the two rollers is such that they touch and run upon each other while in operation.

vImmediately below the rollers D G is another, H, fig. 5, having its bearin gs also in the frame. From the face of this roller proceed ranges of bristles, I, which reach to and brush the faceof the roller'G.

J, iig. 2, is a sexies of points or combs, projecting from the end of the frame, near to the face of the Aroller D, andtouches, or nearly so, the edge of the plate K, which edge,- as will be observed, is brought very close to the face of the roller.

The teeth or comb above referred to is attached to a slide, A', iig. 5, fitted in agroove transverselyA across the end of the frame. One end of said slide projects beyond the side of the frame, into the pulley E, the side of the pulley being chambered out, and in which is xed a cam, B; or other devices may be used, by means of which the slide and teeth are made to vibrate transversely across the frame, foil a purpose hereafter shown.

viz:

The cotton to be cleaned is fed to the machine at the hopper C', drawn between the roller D and the edge of the plate K. The seed, in consequence of their size, being unable to pass with the cotton, are torn from the same by the sharppedge of the plate, and fall down the inclined plate K to the outside of the gin.A The cotton isV carried through by the rubber roller, and thrown out at the farther end of the machine, at the point x, free from the seed, and unbroken in fibre.

In order to prevent the edge of the plate K from becoming gummed, and covered by the lodgment of fragments of cotton, and also to prevent the seed from u remaining at the edge of the plate, in consequence of the fuzzy coat enveloping them, the comb or points J are caused to vibrate, as above described, thereby keeping the edge of the plate and rollerfree and unobstructed. V i

The revolving brush H, being also put in motion by the pulleys N not only removes all dust and fragments'of cotton that may be' inclined to adhere to the rollers, but, acting as a fan, induces a current-of air,

vby which the cleaned cotton is carried out from the machine, and thus the gin is kept clean and free from all obstructions.

The roller D may be constructed entirely of rubber, or it may consist of a core of other material, and cov ered with rubber or some other elastic material, and being secured in the ends of the timbers B, as above said', the roller may be brought close to or removed away from the-edge of the plate, more or less, asmay be required by the adjusting-screws D.

What we claim as our improvement, and desire to secure by Letters Patent, is

1. The rollers D and G, vibrating comb J, and plate K, combined and operating as set forth.

2. In combination with the above, the rotating brush I, or its equivalent, operating substantially as described.
